ABSTRACT

INTRODUCCIÓN: La enfermedad cerebral de pequeño vaso es una causa principal de pérdida funcional, discapacidad y deterioro cognitivo. OBJETIVO: Determinar la prevalencia de la enfermedad de pequeño vaso y características clínicas que se asocian a mayor deterioro funcional, cognitivo y afectivo en adultos mayores con enfermedad cerebrovascular atendidos en el Servicio de Neurología del Hospital Carlos Andrade Marín en el período 2020 ­ 2021. METODOLOGÍA: Estudio observacional, analítico transversal con 80 pacientes mayores de 65 años con enfermedad cerebrovascular previamente diagnosticada. Se determinó cuáles presentaban enfermedad cerebral de pequeño vaso. Se compararon los dos grupos el de enfermedad cerebro vascular isquémico con y sin enfermedad cerebral de pequeño vaso. Se midió el grado de deterioro funcional con escala de Barthel; Lawton y Brody. El deterioro cognitivo con test de Montreal Cognitive Assessment ­Basic, estado afectivo con escala de Yesavage. Se utilizó razón de momios y se consideró significativo un valor p <0,05. Se utilizó el programa Statistical Package for Social Sciences versión 25. RESULTADOS: Los hombres representaron el 51,2%. La edad promedio fue 76,2 años. Prevalencia de enfermedad cerebral de pequeño vaso (87,5%). Escala de Fazekas grado 1 (46,3%), Factores asociados con enfermedad cerebral de pequeño vaso: tabaquismo [RR: 7,27; IC 95%: 1,69-31,3); enfermedad renal crónica [RR: 4,0; IC 95%: 1,01-15,7]. Dependencia moderada [RR: 6,42; IC 95%: 1,02-40,3]. Factores asociados con pérdida funcionalidad: gravedad del ictus. Factores asociados con deterioro cognitivo: infarto con doble territorio. Factores asociados con deterioro afectivo: infarto con doble territorio y síndrome metabólico (p<0,05). CONCLUSIÓN: La enfermedad cerebral de pequeño vaso tiene una elevada prevalencia entre los adultos mayores con enfermedad cerebrovascular y representó un deterioro cognitivo, funcional y afectivo considerable, en relación a los pacientes sin esta enfermedad.


INTRODUCTION: Cerebral small vessel disease is a leading cause of functional loss, disability, and cognitive impairment. OBJECTIVE: To determine the prevalence of small vessel disease and clinical characteristics associated with greater functional, cognitive and affective impairment in older adults with cerebrovascular disease attended at the Neurology Service of the Carlos Andrade Marín Hospital in the period 2020 - 2021. METHODOLOGY: Observational, analytical cross-sectional study with 80 patients over 65 years of age with previously diagnosed cerebrovascular disease. It was determined which patients had cerebral small vessel disease. The two groups of ischemic cerebrovascular disease with and without cerebral small vessel disease were compared. The degree of functional impairment was measured with the Barthel, Lawton and Brody scales. Cognitive impairment was measured with the Montreal Cognitive Assessment-Basic test, and affective state with the Yesavage scale. Odds ratio was used and a p value <0,05 was considered significant. Statistical Package for Social Sciences version 25 was used. RESULTS: Males represented 51,2%. Mean age was 76,2 years. Prevalence of cerebral small vessel disease (87,5%). Fazekas scale grade 1 (46,3%), Factors associated with cerebral small vessel disease: smoking [RR: 7,27; 95% CI: 1,69-31,3); chronic kidney disease [RR: 4,0; 95% CI: 1,01-15,7]. Moderate dependence [RR: 6,42; 95% CI: 1,02-40,3]. Factors associated with loss of function: severity of stroke. Factors associated with cognitive impairment: infarction with double territory. Factors associated with affective impairment: dual territory infarction and metabolic syndrome (p<0.05). CONCLUSION: Cerebral small vessel disease has a high prevalence among older adults with cerebrovascular disease and represented a considerable cognitive, functional and affective deterioration, in relation to patients without this disease.

ABSTRACT

Abstract Background Sjogren-Larsson syndrome (SLS) is a neurocutaneous disease with an autosomal recessive inheritance, caused by mutations in the gene that encodes fatty aldehyde dehydrogenase (ALDH3A2), clinically characterized by ichthyosis, spastic diplegia, and cognitive impairment. Brain imaging plays an essential role in the diagnosis, demonstrating a nonspecific leukoencephalopathy. Data regarding brain atrophy and grey matter involvement is scarce and discordant. Objective We performed a volumetric analysis of the brain of two siblings with SLS with the aim of detecting deep grey matter nuclei, cerebellar grey matter, and brainstem volume reduction in these patients. Methods Volume data obtained from the brain magnetic resonance imaging (MRI) of the two patients using an automated segmentation software (Freesurfer) was compared with the volumes of a healthy control group. Results Statistically significant volume reduction was found in the cerebellum cortex, the brainstem, the thalamus, and the pallidum nuclei. Conclusion Volume reduction in grey matter leads to the hypothesis that SLS is not a pure leukoencephalopathy. Grey matter structures affected in the present study suggest a dysfunction more prominent in the thalamic motor pathways.


Resumo Antecedentes A Síndrome de Sjogren-Larsson (SSL) é uma doença neurocutânea de herança autossômica recessiva, causada por mutações no gene que codifica a aldeído graxo desidrogenase (ALDH3A2), caracterizada clinicamente por ictiose, diplegia espástica e comprometimento cognitivo. A imagiologia cerebral desempenha um papel essencial no diagnóstico, demonstrando uma leucoencefalopatia inespecífica. Dados sobre atrofia cerebral e envolvimento da substância cinzenta são escassos e discordantes. Objetivo Realizamos uma análise volumétrica do cérebro de dois irmãos com SLS com o objetivo de detectar núcleos profundos de substância cinzenta, substância cerebral cinzenta e redução do volume do tronco encefálico nestes pacientes. Métodos Os dados de volume obtidos da ressonância magnética (RM) cerebral dos dois pacientes usando um software de segmentação automática (Freesurfer) foram comparados com os volumes de um grupo controle saudável. Resultados Redução de volume estatisticamente significativa foi encontrada no córtex do cerebelo, no tronco cerebral, no tálamo e nos núcleos pálidos. Conclusão A redução do volume da substância cinzenta leva à hipótese de que a SSL não é uma leucoencefalopatia pura. As estruturas da substância cinzenta afetadas no presente estudo sugerem uma disfunção mais proeminente nas vias motoras talâmicas.

ABSTRACT

Abstract Ketogenic dietary therapies (KDTs) are a safe and effective treatment for pharmacoresistant epilepsy in children. There are four principal types of KDTs: the classic KD, the modified Atkins diet (MAD), the medium-chain triglyceride (MCT) diet, and the low glycemic index diet (LGID). The International Ketogenic Diet Study Group recommends managing KDTs in children with epilepsy. However, there are no guidelines that address the specific needs of the Brazilian population. Thus, the Brazilian Child Neurology Association elaborated on these recommendations with the goal of stimulating and expanding the use of the KD in Brazil.


Resumo As terapias dietéticas cetogênicas (TDC) são um tratamento seguro e eficaz para epilepsia farmacorresistente em crianças. Existem quatro tipos principais de TDCs: a dieta cetogênica (DC) clássica, a dieta de Atkins modificada (DAM), a dieta de triglicerídeos de cadeia média (DTCM) e a dieta de baixo índice glicêmico (DBIG). O Grupo Internacional de Estudos de Dietas Cetogênicas (International Ketogenic Diet Study Group) propõe recomendações para o manejo da DC em crianças com epilepsia. No entanto, faltam diretrizes que contemplem as necessidades específicas da população brasileira. Assim, a Associação Brasileira de Neurologia Infantil elaborou essas recomendações com o objetivo de estimular e expandir o uso da DC no Brasil.

ABSTRACT

Abstract Mutations in SCN8A gene lead to changes in sodium channels in the brain, which are correlated with severe epileptic syndrome. Due to the rarity, there are few studies that support anesthesia in that population. The present study aims to report alternatives to inhalation anesthesia at epileptic encephalopathy. Case report: Male, 4 years old, with SCN8A encephalopathy with surgical indication of orchidopexy. Neuroaxis block was performed and dexmedetomidine was used as a pre-anesthetic and sedation. The anestheticsurgical act was uneventful. Conclusion: The association of neuraxial block and dexmedetomidine proved to be a viable alternative for surgery in patients with SCN8A encephalopathy.

ABSTRACT

Objetivo: Reportamos resultados sobre la efectividad, seguridad y tolerancia del cannabidiol como adyuvante terapéutico en pacientes pediátricos con encefalopatías epilépticas del desarrollo (EED) resistentes al tratamiento farmacológico y no farmacológico tras un seguimiento promedio de 20 meses. Métodos: Se realizó un estudio de cohorte prospectivo para evaluar la eficacia, la seguridad y la tolerancia del aceite de cannabis medicinal enriquecido con CBD añadido a los medicamentos anticonvulsivos estándar en niños con EED resistentes a los medicamentos atendidos en un único centro. Resultados: Entre octubre de 2018 y marzo de 2020, se incluyeron 59 pacientes. La edad media en el momento del inicio del protocolo fue de 10,5 años (rango, 2-17 años). La mediana de la duración del tratamiento fue de 20 meses (rango, 12-32). La mediana de edad en el momento de la primera convulsión fue de 8 meses (rango, 1 día - 10 años). Al final del seguimiento, el 78% de los niños tenía una disminución ≥ 50% en frecuencia de las crisis y el 47,5% tenía una disminución > 75%. Siete pacientes (11,9%) estaban libres de convulsiones. El número de crisis se redujo de una mediana de 305/mes a 90/mes, que supone una reducción media del 57% y una mediana del 71% (p < 0,0001). Los efectos adversos fueron en su mayoría leves o moderados. El CBD se interrumpió en 17 pacientes (28,8%) por falta de respuesta al tratamiento, aumento de la frecuencia de las convulsiones, intolerancia al fármaco o cumplimiento terapéutico insuficiente. Conclusión: En los niños con EED resistentes a los fármacos, el tratamiento a largo plazo del cannabis medicinal enriquecido con CBD como terapia adyuvante resultó ser seguro, bien tolerado y eficaz. Las reducciones sostenidas en la frecuencia de las convulsiones y la mejora de los aspectos de la vida diaria se observaron en comparación con nuestros preliminares (AU)


Objective: We report results on the effectiveness, safety, and tolerance of cannabidiol (CBD) as add-on therapy in children with developmental and epileptic encephalopathies (DEE) resistant to pharmacological and non-pharmacological treatment after a mean follow-up of 20 months. Methods: A prospective cohort study was conducted to evaluate the efficacy, safety, and tolerability of CBD-enriched medical cannabis oil added to standard antiseizure medications in children with drug-resistant DEEs seen at a single center. Results: Between October 2018 and March 2020, 59 patients were included. The median age at protocol initiation was 10.5 years (range, 2-17 years). Median treatment duration was 20 months (range, 12-32). The median age at the time of the first seizure was 8 months (range, 1 day - 10 years). At the end of follow-up, 78% of the children had a decrease ≥ 50% in seizure frequency and 47.5% had a decrease of > 75%. Seven patients (11.9%) were seizure free. The number of seizures was reduced from a median of 305/month to 90/month, accounting for a mean reduction of 57% and a median of 71% (p < 0.0001). Adverse effects were mostly mild or moderate. CBD was discontinued in 17 patients (28.8%) due to lack of response to treatment, increased seizure frequency, drug intolerance, or poor compliance. Conclusion: In children with drug-resistant DEE, long-term treatment with CBD-enriched medicinal cannabis as add-on therapy proved to be safe, well tolerated, and effective. Sustained reductions in seizure frequency and improvement in aspects of daily living were observed compared to our preliminary results (AU)

ABSTRACT

RESUMO A síndrome da encefalopatia posterior reversível é uma rara síndrome clínica e radiológica caracterizada por edema vasogênico da matéria branca dos lobos occipital e parietal, que geralmente são simétricos, resultante de uma manifestação secundária de disfunção aguda do sistema cerebrovascular posterior. Descrevemos um caso de síndrome de encefalopatia posterior reversível secundária à infecção por SARS-CoV-2 em um menino de 9 anos de idade que desenvolveu insuficiência respiratória hipoxêmica aguda e necessitou de ventilação mecânica assistida. A criança desenvolveu síndrome inflamatória multissistêmica e foi monitorada na unidade de terapia intensiva pediátrica, tendo-lhe sido fornecidos ventilação mecânica e agentes vasoativos para suporte hemodinâmico. Além disso, desenvolveu manifestações clínicas pulmonares e extrapulmonares juntamente de manifestações neuropsiquiátricas que necessitavam de seguimento cuidadoso, tendo sido verificadas por ressonância magnética cerebral para intervenção oportuna. Atualmente, há poucos relatos de crianças com síndrome da encefalopatia posterior reversível associada à síndrome inflamatória multissistêmica.


ABSTRACT Posterior reversible encephalopathy syndrome is a rare clinical and radiological syndrome characterized by vasogenic edema of the white matter of the occipital and parietal lobes, which are usually symmetrical, resulting from a secondary manifestation of acute dysfunction of the posterior cerebrovascular system. We describe a case of posterior reversible encephalopathy syndrome secondary to SARS-CoV-2 infection in a 9-year-old boy who developed acute hypoxemic respiratory failure and required assisted mechanical ventilation. The child developed multisystem inflammatory syndrome, and he was monitored in the pediatric intensive care unit and was provided mechanical ventilation and vasoactive agents for hemodynamic support. Additionally, he developed pulmonary and extrapulmonary clinical manifestations along with neuropsychiatric manifestations that required close follow-up and were verified using brain magnetic resonance imaging for timely intervention. Currently, there are few reports of children with posterior reversible encephalopathy syndrome associated with multisystem inflammatory syndrome.

ABSTRACT

RESUMEN El síndrome de encefalopatía posterior reversible es una entidad clínico radiológica caracterizada por manifestaciones neurológicas de inicio insidioso y progresivo producido por alteraciones de la perfusión vascular cerebral. Se presentan 2 casos de pacientes con lupus eritematoso sistémico (LES) que desarrollan el síndrome de encefalopatía posterior reversible por hipertensión arterial refractaria. Ambos casos acuden por un cuadro de dificultad respiratoria y edema generalizado, con alteraciones de perfil renal e hipertensión arterial refractaria. El primero se trata de una paciente conocida portadora de lupus eritematoso sistémico en tratamiento irregular y enfermedad renal crónica en tratamiento hemodialítico que presenta alteraciones visuales y convulsiones. El segundo se trata de una paciente con LES en tratamiento irregular y nefritis lúpica sin tratamiento que también presenta alteraciones visuales y convulsiones. Los estudios de neuroimagen en ambos pacientes muestran lesiones a nivel occipital compatibles con el síndrome de encefalopatía posterior reversible. Con la mejoría de las cifras tensionales revirtieron las manifestaciones neurológicas, excepto en el primer caso en el cual persistieron las convulsiones.


ABSTRACT Posterior reversible encephalopathy syndrome is a clinical and radiological entity characterized by neurological manifestations of insidious and progressive onset caused by alterations in cerebral vascular perfusion. We present two cases of patients with systemic lupus erythematosus (SLE) who developed posterior reversible encephalopathy syndrome due to refractory arterial hypertension. Both cases came due to respiratory distress and generalized edema, with alterations in the renal profile and refractory arterial hypertension. The first is a known female patient with systemic lupus erythematosus in irregular treatment and chronic kidney disease in hemodialysis treatment who presented visual disturbances and seizures. The second is a female patient with SLE in irregular treatment and untreated lupus nephritis who also presented visual disturbances and seizures. Neuroimaging studies in both patients show lesions at the occipital level compatible with posterior reversible encephalopathy syndrome. With the improvement in the blood pressure values, the neurological manifestations reverted in the second case but in the first case the seizures persisted.

ABSTRACT

Resumo As doenças neurometabólicas hereditárias representam um desafio diagnóstico e precisam de classificações eficientes para sua compreensão. São um grupo de doenças raras, mas atingem pelo menos um a cada mil nascimentos. Algumas têm possibilidade terapêutica. Os quadros clínico e radiológico são variáveis e, às vezes, superponíveis, a depender da fase da doença. Por isso, observam-se na literatura vários tipos de classificações, algumas de difícil aplicação prática. O objetivo deste estudo é ilustrar a classificação das doenças neurometabólicas hereditárias baseada exclusivamente em achados radiológicos. Trata-se de um estudo retrospectivo a partir de exames de imagem do sistema nervoso central, particularmente de crianças, realizados em uma rede de hospitais. Todos os casos foram estudados por tomografia computadorizada multidetectores e/ou ressonância magnética, tendo sido avaliados por dois neurorradiologistas. Consideraram-se os casos com diagnóstico definitivo. A classificação propõe 10 subgrupos, de acordo com os achados radiológicos. Todos os casos estudados apresentaram, pelo menos, um desses achados. Na maioria dos casos observou-se mais de um achado, o que aumentou a especificidade e restringiu os diagnósticos diferenciais. Após avaliar os dados de literatura e os deste estudo, demonstra-se que é possível classificar as doenças neurometabólicas hereditárias pelo aspecto radiológico, o que favorece um diagnóstico definitivo.


Abstract Inherited neurometabolic disorders represent a diagnostic challenge, and an efficient classification system is needed in order to improve the understanding of these diseases. Although they constitute a group of rare diseases, they have a collective incidence of at least one case per 1,000 live births. Some inherited neurometabolic disorders are treatable. The clinical and radiological presentations are variable and sometimes overlap, depending on the stage of the disease. Therefore, a number of classification systems have been devised, some of which are difficult to apply in practice. The aim of this study was to illustrate a classification system for inherited neurometabolic disorders, based exclusively on radiological findings. This was a retrospective study of imaging examinations of the central nervous system, particularly of children, performed in a network of hospitals. All of the cases were studied by multidetector computed tomography, magnetic resonance imaging, or both, the images having been obtained by two neuroradiologists. We included only cases in which a definitive diagnosis was made. The classification system separates the relevant radiological findings into 10 categories. All of the cases studied presented at least one of those findings. In most of the cases, more than one finding was observed, which increased specificity and narrowed the differential diagnosis. Data from the literature and from this study demonstrate that it is possible to classify inherited neurometabolic disorders by their radiological aspects, which favors a definitive diagnosis.

ABSTRACT

RESUMO Uma mulher com 63 anos de idade compareceu ao pronto-socorro com história aguda de febre, prostração e dispneia. Recebeu diagnóstico de quadro grave da COVID-19 e síndrome do desconforto respiratório agudo. Apesar de suporte clínico intensivo, cumpriu os critérios para ser submetida à oxigenação venovenosa por membrana extracorpórea. No dia 34, após 7 dias de desmame da sedação com evolução positiva de seu quadro neurológico, apresentou uma crise tônico-clônica generalizada limitada, não relacionada com desequilíbrio hidroeletrolítico ou metabólico, que levou à necessidade de investigação diagnóstica. Seus exames de imagem cerebral revelaram síndrome da encefalopatia posterior reversível. Este caso enfatiza a questão das complicações neurológicas em pacientes com COVID-19 grave e a importância do diagnóstico e suporte precoces.


ABSTRACT A 63-year-old woman presented to the emergency department with an acute history of fever, prostration and dyspnea. She was diagnosed with severe COVID-19 acute respiratory distress syndrome and, despite optimized critical care support, met the indications for veno-venous extracorporeal membrane oxygenation. On day 34, after 7 days of wean sedation with a positive evolution of neurologic status, she presented a limited generalized tonic-clonic seizure not related to hydroelectrolytic or metabolic imbalance, which led to a diagnostic investigation; her brain imaging tests showed a posterior reversible encephalopathy syndrome. This case emphasizes the issue of neurological complications in patients with severe COVID-19 infection and the importance of early diagnosis and support.

ABSTRACT

RESUMEN Introducción: Síndrome de encefalopatía posterior reversible PRES (también conocido como síndrome de leucoencefalopatía posterior reversible) se presenta con síntomas de inicio rápido como cefalea, convulsiones, alteración de la conciencia y alteración visual. A menudo, pero de ninguna manera siempre, se asocia con la hipertensión aguda. Metodología: Estudio de tipo revisión sistemática de la literatura. Se realizó una revisión sistemática de la literatura en las bases de datos PubMed/MEDLINE, LILACS y CICCO utilizando la sintaxis "Posterior reversible encephalopathy syndrome AND treatment". Los límites de búsqueda fueron publicaciones hechas en los últimos cinco años (2013-2020). Resultados: Se evaluaron 235 textos completos de los cuales finalmente se seleccionaron seis, esto teniendo en cuenta que los demás artículos no mencionaban de forma explícita el tratamiento, o eran redundantes con respecto a otros ya incluidos, teniendo en cuenta que el PRES tiene un manejo sintomático más que un tratamiento específico. Discusión: Síndrome de Encefalopatía Posterior Reversible (PRES) no tiene un tratamiento específico, sino más bien tiene un tratamiento sintomático lo que hace fundamental conocer las causas subyacentes al PRES ya que esa es la terapéutica a seguir, brindar el mejor tratamiento para lo que está causando este síndrome, de allí la importancia de conocer a fondo la etiología.


ABSTRACT Introduction: Posterior reversible encephalopathy syndrome PRES (also known as posterior reversible leukoencephalopathy syndrome) presents with rapid-onset symptoms such as headache, seizures, altered consciousness, and visual impairment. Often, but by no means always, it is associated with acute hypertension. Methods: Systematic literature review type study. A systematic review of the literature was carried out in the PubMed / MEDLINE, LILACS and CICCO databases using the syntax "Posterior reversible encephalopathy syndrome AND treatment". The search limits were publications made in the last five years (2013-2020). Results: 235 full texts were evaluated, of which six were finally selected, taking into account that the other articles did not explicitly mention the treatment, or were redundant with respect to others already included, taking into account that the PRES has symptomatic rather than specific treatment. Discussion: Posterior Reversible Encephalopathy Syndrome (PRES) does not have a specific treatment, but rather has a symptomatic treatment, which makes it essential to know the underlying causes of PRES since that is the therapy to follow, to provide the best treatment for what is causing this syndrome, hence the importance of fully understanding the etiology.

ABSTRACT

ABSTRACT The Paraguayan War ended 150 years ago. Back then, there were outbreaks of combatants' limb weakness and tingling related to "palustrian cachexia", not clearly funded at the time on nutritional deficiency, the use of native flora to feed troops, and alcoholism. We report a case of a soldier with ascending paralysis, mental confusion and finally tetraplegia with preserved oculomotricity. This would probably be a case of locked-in syndrome (LIS) due to Gayet-Wernicke's encephalopathy consequent to thiamine deficiency. The role of thiamine in the peripheral or central nervous system expression was shown decades later to be related to poor diet, or use of foods containing thiaminase or thiamine antagonists, worsened by the fact that the bodily stores of thiamine are restricted, and deficits may grow fast.


RESUMO A Guerra do Paraguai terminou há 150 anos. Houve surtos de fraqueza dos membros dos combatentes e parestesias relacionadas à "caquexia palustre", não claramente fundamentados na época sobre deficiência nutricional, o uso da flora nativa para alimentar as tropas e o alcoolismo. Referimo-nos a um caso de um militar com paralisia ascendente, confusão mental e finalmente tetraplegia com oculomotricidade preservada. Esse relato seria provavelmente devido a um caso de "síndrome do encarceramento" secundário à encefalopatia de Gayet-Wernicke consequente à deficiência de tiamina. O papel da tiamina na expressão periférica ou do SNC foi previsto décadas mais tarde em relação a uma dieta pobre, ou ao uso de alimentos contendo tiamina ou antagonistas da tiamina, agravado pelo fato de que as reservas corporais de tiamina são restritas, e os déficits podem se manifestar rapidamente.

ABSTRACT

ABSTRACT Background: In 2019, the world witnessed the emergence of a new type of coronavirus - the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The spectrum of coronavirus disease 2019 (COVID-19) is variable, and amongst its manifestations are neurological implications. Objective: This report aimed to describe electroencephalographic findings in COVID-19 patients from a general tertiary hospital in São Paulo, Brazil. Methods: It was a retrospective, observational, and non-interventional study. Data were collected anonymously, comprising inpatients from Mar 1 to Jun 30, 2020, either confirmed (positive RT-PCR) or probable cases (CO-RADS 4/5) who had performed EEG during hospitalization. Results: Twenty-eight patients were enrolled, 17 (60.7%) women and 11 men, with a median age of 58 (minimum and maximum: 18-86; IQR 23.5). COVID-19 diagnosis was confirmed in 22 (78.5%). Twenty-one patients (75%) had severe disease, requiring mechanical ventilation due to acute respiratory distress syndrome (ARDS); 16 (57.1%) patients developed adjunct sepsis throughout hospitalization. There was no specific pattern found for COVID-19 in EEG. No patients presented with status epilepticus or electrographic events; most patients developed an encephalopathic pattern, as seen in most studies, with a high prevalence of altered mental status as an indication for EEG. Adjunct sepsis was associated with higher mortality. Conclusions: EEG presents as a useful tool in the context of COVID-19, as in other conditions, to differentiate nonconvulsive status epilepticus (NCSE) from encephalopathy and other causes of mental status alterations. Further studies are required to analyze whether there might be a specific EEG pattern to the disease.


RESUMO Antecedentes: Em 2019, testemunhou-se o surgimento de um novo tipo de coronavírus - o coronavírus associado à síndrome da angústia respiratória tipo 2 (SARS-CoV-2). O espectro da doença associada ao novo coronavírus, a COVID-19, é variável e, dentre suas manifestações, há implicações neurológicas. Objetivos: O presente estudo objetivou descrever achados eletroencefalográficos em pacientes com COVID-19 internados em um hospital terciário em São Paulo. Métodos: Tratou-se de estudo observacional, retrospectivo e não-intervencionista, realizado por meio de coleta anônima e retrospectiva de dados de prontuário médico de pacientes com diagnóstico confirmado (RT-PCR positivo) ou provável (CO-RADS 4 ou 5), que realizaram eletroencefalograma durante internação hospitalar. Resultados: Vinte e oito pacientes foram elencados, 17 (60,7%) mulheres e 11 homens. O diagnóstico de COVID-19 foi confirmado em 22 (78,5%) dos casos. Dos pacientes, 21 (75%) apresentaram a doença, requerendo suporte ventilatório, e 16 (57,1%) desenvolveram sepse sobreposta. Não houve padrão específico de EEG para COVID-19, e nenhum paciente apresentou estado de mal epiléptico ou crise eletrográfica; a maioria desenvolveu padrão de encefalopatia, com alentecimento da atividade cerebral, sendo a alta prevalência de alteração de estado mental a indicação para o exame. A sepse sobreposta foi associada a um pior desfecho, com maior mortalidade. Conclusão: No contexto da COVID-19, o EEG figura como ferramenta importante, auxiliando, como em outras condições, na diferenciação entre estado de mal epiléptico, encefalopatia e outras causas de alteração do estado mental. Estudos adicionais são necessários para avaliar a existência de padrão específico de alteração eletroencefalográfica na COVID-19.

ABSTRACT

RESUMO Uma mulher com 37 anos de idade, gestante de 35 semanas, foi admitida em um hospital local em razão de epistaxe grave, que resultou em choque e em necessidade de realização de cesárea emergencial. Após falha do tamponamento para controlar a hemorragia, decidiu-se por tratamento angiográfico. Após o procedimento, ela foi admitida à unidade de terapia intensiva neurocrítica, encontrando-se confusa e agitada, com necessidade de sedação e intubação orotraqueal. Na unidade de terapia intensiva, as investigações incluíram exames de ressonância magnética, punção lombar com painel viral, eletroencefalograma, testes para autoimunidade e avaliações hidroeletrolítica e metabólica. O exame de ressonância magnética mostrou área puntiforme restrita na corona radiata esquerda nas sequências de imagens pesadas em difusão, além de leve edema cortical posterior (sem restrição à difusão), e o eletroencefalograma mostrou atividade lenta difusa moderada, atividade frontoparietal lenta e escassos componentes paroxísticos associados no hemisfério esquerdo. Outros exames não mostraram alterações relevantes. Por causa da relação temporal e da história clínica, assim como imagens de ressonância magnética, formulou-se o diagnóstico de encefalopatia induzida por contraste. A sedação foi retirada após 2 dias na unidade de terapia intensiva, e a paciente foi extubada, verificando-se completa recuperação neurológica dentro das 24 horas seguintes.


ABSTRACT A 37-year-old woman (35 weeks pregnant) was admitted to a local hospital due to severe epistaxis resulting in shock and the need for emergency cesarean section. After failure to tamponade the bleeding, angiographic treatment was provided. After the procedure, she was admitted to the neurocritical intensive care unit and was confused and agitated, requiring sedation and endotracheal intubation. In the intensive care unit, diagnostic investigations included brain magnetic resonance imaging, lumbar puncture with viral panel, electroencephalogram, tests for autoimmunity, and hydroelectrolytic and metabolic evaluations. Magnetic resonance imaging showed a puntiform restricted diffusion area on the left corona radiata on diffusion weighted imaging and mild cortical posterior edema (without restricted diffusion), and an electroencephalogram showed moderate diffuse slow activity and fronto-temporal slow activity of the left hemisphere with associated scarce paroxysmal components. The other exams did not show any relevant alterations. Due to the temporal relationship, the clinical history and the magnetic resonance imaging results, a diagnosis of contrast-induced encephalopathy was made. After 2 days in the intensive care unit, sedation was withdrawn, the patient was extubated, and total neurological recovery was verified within the next 24 hours.

ABSTRACT

RESUMEN La encefalomielitis aguda diseminada (ADEM) es una enfermedad desmielinizante del sistema nervioso central (SNQ, de baja prevalencia, con predominio de presentación en población pediátrica. Describir y revisar la presentación clínica de un paciente con ADEM, su proceso diagnóstico y el manejo terapéutico, de acuerdo con la evidencia disponible. Adolescente masculino de 17 años, sin antecedentes de importancia, con cuadro de cefalea hemicraneal derecha, tipo punzada, de alta intensidad, dos semanas de evolución y posterior compromiso agudo neurológico multifocal con encefalopatía, hemiparesia y diplopía. Se realiza estudio con resonancia de cerebro contrastada que pone en evidencia lesiones hiperintensas a nivel de tallo, cerebelo y ganglios basales. Estas lesiones son asimétricas, unilaterales y agudas y siguen el trayecto vascular de la arteria cerebelosa posteroinferior (PICA), sin restricción a la difusión o cambios en mapa ADC. Inicialmente se sospecha evento cerebrovascular (ECV) y se estudia con angiorresonancia normal, ayudas diagnósticas para causas cardioembólicas y trombofilias negativas. Al considerar lesiones no se sugieren cambios de origen isquémico, pero si desmielinizantes. Se inicia manejo con pulsos de metilprednisolona con resolución de hemiparesia y encefalopatía. En seguimiento a 18 meses, el paciente no ha presentado nuevos eventos clínicos o radiológicos. La ADEM es una patología infrecuente en la edad pediátrica, con un diagnóstico basado en la clínica y hallazgos imagenológicos en resonancia magnética. Su presentación clínica puede ser inespecífica y como en este caso simular enfermedad cerebrovascular, y el tratamiento se basa en inmunomoduladores, principalmente corticoides, con una tasa de recuperación favorable en las series previamente reportadas.


SUMMARY Acute disseminated encephalomyelitis (ADEM) is a low-prevalence demyelinating disease of the central nervous system (CNS) with a predominance of presentation in the pediatric population. To describe and review the clinical presentation of a patient with ADEM, its diagnostic process and therapeutic management according to the available evidence. A 17-year-old male adolescent, with a 2-week history of high-intensity right-sided headache, stitching type, subsequent acute multifocal neurological compromise with encephalopathy, hemiparesis, and diplopia. A contrast-enhanced brain resonance study with evidence of hyperintense lesions at the level of the stem, cerebellum, and basal ganglia, asymmetric, unilateral, acute, following the vascular path of the posteroinferior cerebellar artery (PICA), but without restriction to diffusion or changes on the ADC map, so that an initial suspicion of cerebrovascular event (CVD) is made, studying with normal angioresonance, diagnostic aids for negative cardioembolic causes and thrombophilias. Considering that lesions do not suggest changes of ischemic origin, but if they are demyelinating, management with methylprednisolone pulses with resolution of hemiparesis and encephalopathy is initiated. In the 18-month follow-up, the patient has not presented new clinical or radiological events. ADEM, is an infrequent pathology in pediatric age, with a diagnosis based on the clinic and magnetic resonance imaging findings, its clinical presentation may be nonspecific and as in this case simulate cerebrovascular disease, the treatment is based on immunomodulatory treatment, mainly corticosteroids, with a favorable recovery rate in the previously reported series.

ABSTRACT

Resumo Fundamento As doenças cerebrovasculares (DCBV) constituem a segunda causa de mortes no mundo. Objetivo Analisar a tendência da mortalidade por DCVB no Brasil (1996-2015) e associação com o índice de desenvolvimento humano (IDH) e o índice de vulnerabilidade social (IVS). Métodos Trata-se de estudo ecológico envolvendo as taxas de mortalidade padronizadas por DCBV. Os dados dos óbitos foram obtidos do Sistema de Informações sobre Mortalidade e os dados populacionais, do Instituto Brasileiro de Geografia e Estatística. Para as análises temporais, foi utilizado o modelo de regressão por pontos de inflexão, sendo calculado o percentual de variação anual (annual percent change [APC]) e médio do período (average annual percent change [AAPC]), com intervalo de confiança de 95% e significância de 5%. As tendências foram classificadas em crescente, decrescente ou estacionária. O modelo de regressão multivariada foi utilizado para testar a associação entre a mortalidade por DCBV, IDH e IVS. Resultados Foram registrados 1.850.811 óbitos por DCBV no período estudado. Observou-se redução da taxa de mortalidade nacional (APC: -2,4; p = 0,001). Vinte unidades federativas apresentaram tendências significativas, sendo 13 de redução, incluindo todos das regiões Centro-Oeste (n = 4), Sudeste (n = 4) e Sul (n = 3). O IDH teve associação positiva e o IVS, associação negativa com a mortalidade (p = 0,046 e p = 0,026, respectivamente). Conclusão O estudo mostrou comportamento epidemiológico desigual da mortalidade entre as regiões, sendo maior nos estados do Sudeste e Sul, porém com tendência significativa de redução, e menor nos estados do Norte e Nordeste, mas com tendência significativa de crescimento. O IDH e o IVS associaram-se com a mortalidade. (Arq Bras Cardiol. 2021; 116(1):89-99)


Abstract Background Cerebrovascular diseases (CBVD) are the second major cause of death in the world. Objective To analyze the mortality trend of CBVD in Brazil (1996 to 2015) and its association with Human Development Index (HDI) and the Social Vulnerability Index (SVI). Methods This is an ecological study. We analyzed the mortality rate standardized by CBVD. Death data were obtained from the Mortality Information System (SIM) and populational data from the Brazilian Institute of Geography and Statistics (IBGE). The model of regression by inflection points (Joinpoint regression) was used to perform the temporal analysis, calculating the Annual Percent Change (APC) and Average Annual Percent Change (AAPC), with 95% of confidence interval and a significance of 5%. Trends were classified as increasing, decreasing or stationary. A multivariate regression model was used to analyze the association between mortality by CBVD, HDI and SVI. Results During this period, 1,850,811 deaths by CBVD were recorded. We observed a reduction in the national mortality rate (APC -2.4; p = 0.001). Twenty federation units showed a significant trend, of which 13 showed reduction, including all states in the Midwest (n=4), Southeast (n=4) and South (n=3). The HDI was positively associated and the SVI was negatively associated with mortality (p = 0.046 and p = 0.026, respectively). Conclusion An unequal epidemiological course of mortality was observed between the regions, being higher in the Southeast and South states, with a significative tendency of reduction, and lower in the North and Northeast states, but with a significative tendency of increase. HDI and SVI showed an association with mortality. (Arq Bras Cardiol. 2021; 116(1):89-99)

ABSTRACT

RESUMEN El reporte de manifestaciones neurológicas en pacientes con COVID-19 se ha incrementado significativamente en los últimos meses. Sin embargo, los hallazgos de neuroimágenes han sido pobremente documentados debido a las restricciones por la necesidad de aislamiento de estos pacientes. Se reportan dos casos de pacientes con COVID-19 con clínica neurológica, a quienes se les realizó estudios de imagen cerebral y presentaron hallazgos atípicos en la resonancia magnética de encéfalo. Es necesario descripciones más detalladas y mejor documentadas de las manifestaciones neurológicas en los pacientes hospitalizados con COVID-19 y sus respectivos correlatos en neuroimágenes para lograr un mejor conocimiento de la enfermedad.


ABSTRACT Reports describing neurological manifestations in patients with COVID-19 have substantially increased in the past months. Nevertheless, findings from neuroimaging studies have been poorly documented because of restrictions due to the need for isolating such patients. Two cases of patients with COVID-19 and clinical neurological manifestations are reported. They underwent brain imaging studies and atypical findings were made in cerebral magnetic resonance imaging. It is necessary to have more detailed and better documented descriptions of neurological manifestations in patients hospitalized with COVID-19 and their respective neuroimaging correlates in order to obtain better knowledge of this condition.

ABSTRACT

Creutzfeldt and Jakob's disease (CJD) has its initial milestone in the publication issued 100 years ago that precipitated its better clinical-pathological and etiological understanding. Now, it is established that it belongs to the group of the prion diseases or transmissible spongiform encephalopathies family. CJD is itself divided into several types, the most common being sporadic that is further subdivided according to the anatomoclinical expression, but mainly due to its aetiology regarding prionic protein or genotype.


A doença de Creutzfeldt e Jakob (CJD) tem seu marco inicial na publicação emitida há 100 anos que precipitou seu melhor entendimento clínico- patológico e etiológico. Agora, está estabelecido que pertence ao grupo da família das doenças de príons ou encefalopatias espongiformes transmissíveis. A própria CJD se divide em vários tipos, sendo o mais comum o esporádico que também se subdivide de acordo com a expressão anatomoclínica, mas principalmente devido à sua etiologia em relação à proteína priônica ou genótipo.

ABSTRACT

ABSTRACT Background: More than one-third of COVID-19 patients present neurological symptoms ranging from anosmia to stroke and encephalopathy. Furthermore, pre-existing neurological conditions may require special treatment and may be associated with worse outcomes. Notwithstanding, the role of neurologists in COVID-19 is probably underrecognized. Objective: The aim of this study was to report the reasons for requesting neurological consultations by internists and intensivists in a COVID-19-dedicated hospital. Methods: This retrospective study was carried out at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Brazil, a 900-bed COVID-19 dedicated center (including 300 intensive care unit beds). COVID-19 diagnosis was confirmed by SARS-CoV-2-RT-PCR in nasal swabs. All inpatient neurology consultations between March 23rd and May 23rd, 2020 were analyzed. Neurologists performed the neurological exam, assessed all available data to diagnose the neurological condition, and requested additional tests deemed necessary. Difficult diagnoses were established in consensus meetings. After diagnosis, neurologists were involved in the treatment. Results: Neurological consultations were requested for 89 out of 1,208 (7.4%) inpatient COVID admissions during that period. Main neurological diagnoses included: encephalopathy (44.4%), stroke (16.7%), previous neurological diseases (9.0%), seizures (9.0%), neuromuscular disorders (5.6%), other acute brain lesions (3.4%), and other mild nonspecific symptoms (11.2%). Conclusions: Most neurological consultations in a COVID-19-dedicated hospital were requested for severe conditions that could have an impact on the outcome. First-line doctors should be able to recognize neurological symptoms; neurologists are important members of the medical team in COVID-19 hospital care.


RESUMO Introdução: Mais de um terço dos pacientes com COVID-19 apresentam sintomas neurológicos que variam de anosmia a AVC e encefalopatia. Além disso, doenças neurológicas prévias podem exigir tratamento especial e estar associadas a piores desfechos. Não obstante, o papel dos neurologistas na COVID-19 é provavelmente pouco reconhecido. Objetivo: O objetivo deste estudo foi relatar os motivos para solicitar consultas neurológicas por clínicos e intensivistas em um hospital dedicado à COVID-19. Métodos: Estudo retrospectivo realizado no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Brasil, um centro dedicado à COVID-19 com 900 leitos (incluindo 300 leitos para unidades de terapia intensiva). O diagnóstico de COVID-19 foi confirmado por SARS-CoV-2-RT-PCR em swabs nasais. Todas as interconsultas de neurologia hospitalar entre 23 de março e 23 de maio de 2020 foram analisadas. Os neurologistas realizaram o exame neurológico, avaliaram todos os dados disponíveis para diagnosticar a patologia neurológica e solicitaram exames adicionais conforme necessidade. Diagnósticos difíceis foram estabelecidos em reuniões de consenso. Após o diagnóstico, os neurologistas participaram da condução dos casos. Resultados: Foram solicitadas consultas neurológicas para 89 de 1.208 (7,4%) em pacientes internados por COVID-19 durante o período. Os principais diagnósticos neurológicos incluíram: encefalopatia (44,4%), acidente vascular cerebral (16,7%), doenças neurológicas prévias (9,0%), crises epilépticas (9,0%), transtornos neuromusculares (5,6%), outras lesões encefálicas agudas (3,4%) e outros sintomas leves inespecíficos (11,2%). Conclusões: A maioria das consultas neurológicas em um hospital dedicado à COVID-19 foi solicitada para condições graves que poderiam afetar o desfecho clínico. Os médicos na linha de frente devem ser capazes de reconhecer sintomas neurológicos. Os neurologistas são membros importantes da equipe médica no atendimento hospitalar à COVID-19.

ABSTRACT

ABSTRACT Background: Generalized periodic discharges (GPDs) are rare patterns that can be found in long-term electroencephalographic monitoring in critical patients. These patterns have been correlated with non-seizure crisis and non-convulsive status epilepticus, associated with poor prognosis. Objective: To compare the outcome between patients who developed GPDs and patients with other abnormalities in long-term electroencephalographic monitoring. Methods: A retrospective study was performed by analyzing the medical records of 112 patients over 18 years who developed GPDs during long-term electroencephalographic monitoring (12‒16 hours of monitoring) in the intensive care unit of a general hospital, compared with a group that had only nonspecific abnormalities in the monitoring. Results: Age and cardiorespiratory arrest (CA) were risk factors for death - OR 1.04 (95% CI 1,02 - 1,07) and p<0.001; OR 3.00 (95% CI 1,01 - 8,92) and p=0.046, respectively. It was not possible to evaluate if GPDs alone were associated with an unfavorable outcome or would be a bias for the development of CA in these patients. However, of the six isolated GPDs cases, 2/3 evolved to death, showing a tendency to worse prognosis. A significant difference (p=0.031) was observed for a worse outcome when comparing the group of 28 patients who presented GPD or CA with the other group which did not present any of these variables; of these 28 patients, 20 (71.4%) died. Conclusions: The presence of post-CA GPDs was associated with worse prognosis, but it was not clear whether these patterns are independent factors of an unfavorable evolution.


RESUMO Introdução: As descargas periódicas generalizadas (DPG) são padrões raros que podem ser encontrados durante monitorização eletroencefalográfica prolongada (MEP) em pacientes críticos. Esses padrões têm sido correlacionados com crises não convulsivas e estado de mal epiléptico não convulsivo, associados a um pior prognóstico. Objetivo: Comparar o desfecho entre pacientes que desenvolveram DPG e pacientes com anormalidades inespecíficas na MEP. Métodos: Foi realizado um estudo retrospectivo através da análise dos prontuários de 112 pacientes acima de 18 anos que desenvolveram DPG durante MEP (de 12‒16 horas de monitorização) na unidade de terapia intensiva de um hospital geral, comparando com um grupo que apresentou apenas anormalidades inespecíficas na MEP. Resultados: As variáveis idade e parada cardiorrespiratória (PCR) se mostraram como fatores de risco estatisticamente significativos para óbito - OR 1,04 (IC 95% 1,02 - 1,07) e p<0,001; OR 3,00 (IC 95% 1,01 - 8,92) e p=0,046, respectivamente. Não foi possível avaliar se DPG isoladamente se associaram a um desfecho desfavorável ou seriam um viés para o desenvolvimento de PCR nesses pacientes. Porém, dos seis casos de DPG isoladas, 2/3 evoluíram para óbito, o que revela uma tendência a pior prognóstico. Foi observada diferença significativa (p=0,031) para pior desfecho ao comparar o grupo de 28 pacientes que apresentou DPG ou PCR com o outro grupo que não apresentou nenhuma dessas variáveis, sendo que desses 28 pacientes, 20 (71,4%) foram a óbito. Conclusões: A presença de DPG pós-PCR está associada a pior prognóstico, porém não ficou claro se esses padrões são fatores independentes de evolução desfavorável.
